When a God of Destruction Was Reincarnated in Tensura:

The warm morning sunlight bathed the village of Tempest as its residents gathered in a wide clearing to witness the spar between Rimuru and Hakuro. The newly evolved Kijins stood with awe at their own strength but were equally curious to see how their master would fare against Hakuro, the most skilled swordsman among them.

Hakuro, despite his older appearance, exuded a sharp and focused aura. His white hair swayed slightly in the gentle breeze, and his grip on the wooden sword was firm but relaxed, a testament to his mastery. On the other hand, Rimuru stood casually, holding his makeshift wooden blade with an air of confidence.

Benimaru stepped into the center of the clearing, raising one hand. "Alright, the rules are simple. No real swords, no lethal strikes, and no magic. First to land a clean, decisive strike wins."

Rimuru glanced at Hakuro, smiling faintly. "I've been looking forward to this. Show me what it means to be a master swordsman."

Hakuro chuckled softly, his golden eyes narrowing. "Prepare yourself, Rimuru-sama. I won't hold back, even against you."

The two took their positions, standing about 50 feet apart. A tense silence filled the air, broken only by the rustling of leaves and the occasional murmur from the crowd.

"Ready?" Benimaru's voice rang out. "Begin!"

The First Clash

In an instant, both fighters dashed forward, closing the distance in the blink of an eye. Hakuro's movement was fluid, like a leaf gliding on water. His wooden blade came down in a clean, precise arc aimed at Rimuru's shoulder. Rimuru barely managed to sidestep, raising his blade to block, the impact sending a jolt through his arms.

Hakuro didn't let up, pivoting smoothly to deliver a horizontal slash. Rimuru ducked under it, but Hakuro immediately followed with a feint—pulling back his blade as if to slash downward, then thrusting forward instead.

"Great Sage, analyze his movements!" Rimuru thought, twisting his body to the side to avoid the thrust.

"Understood. Analyzing Hakuro's stance and attack patterns. Adjusting countermeasures in real-time."

The Exchange Intensifies

Rimuru retaliated with a quick upward strike, but Hakuro effortlessly parried it, his blade snapping forward in a riposte aimed at Rimuru's ribs. Rimuru blocked it, though the force of Hakuro's strike pushed him back a few steps.

The crowd watched in awe, their eyes darting back and forth as the two moved at incredible speeds.

"I've never seen Hakuro fight this seriously!" Shion exclaimed, her hands clenched in excitement. "Rimuru-sama is holding his own!"

Shuna nodded, her expression calm but intrigued. "It's amazing. Rimuru-sama is adapting so quickly to Hakuro's techniques."

Rimuru Adapts

As the spar continued, Rimuru began to move more fluidly. Great Sage was working overtime, integrating techniques from Rimuru's memories with Hakuro's movements. Each time Hakuro executed a slash, thrust, or feint, Rimuru adapted a little more.

Hakuro launched a series of rapid slashes, each one faster and more precise than the last. Rimuru blocked, deflected, and sidestepped, his movements becoming more seamless. Finally, Rimuru saw an opening and stepped in, aiming a strike at Hakuro's chest.

But Hakuro smirked and spun, using the momentum to redirect Rimuru's blade harmlessly away. "Not bad, Rimuru-sama. You're starting to read my moves. But you'll need to do better."

Testing Each Other

Rimuru grinned, stepping back to reset. "You're not making this easy, old man. But I like a challenge."

Hakuro chuckled. "Good. A blade grows dull without challenge."

The next exchange was a blur of motion. Hakuro feinted high and slashed low, forcing Rimuru to leap back. Rimuru countered with a downward strike, but Hakuro sidestepped and thrust forward. Rimuru twisted mid-air, narrowly avoiding the strike, and retaliated with a spinning horizontal slash. Hakuro blocked it with the flat of his blade, their wooden swords locking for a brief moment.

"Impressive, Rimuru-sama," Hakuro said, his voice calm despite the intensity of their clash. "You've already closed the gap between us."

"Don't flatter me yet," Rimuru replied, pushing against Hakuro's blade before disengaging. "I'm just getting started."

The Final Strike

Hakuro shifted his stance, holding his sword at an angle that Rimuru hadn't seen before. Great Sage immediately chimed in.

"Warning: Hakuro is preparing a finishing move. Calculating optimal response strategy."

"Bring it on," Rimuru said, gripping his sword tightly.

Hakuro dashed forward with blinding speed, his blade flashing in an intricate series of slashes. Rimuru's eyes widened as he parried the first two strikes, sidestepped the third, and ducked under the fourth.

"Now!" Rimuru thought, stepping in to counter. He brought his blade down in a decisive strike aimed at Hakuro's torso.

But Hakuro twisted at the last moment, deflecting Rimuru's blade and spinning behind him. Before Rimuru could react, Hakuro's wooden sword tapped lightly against his shoulder.

"Match," Hakuro said, lowering his blade.

Aftermath

The crowd erupted into cheers, amazed by the intensity of the spar. Rimuru laughed, rubbing his shoulder where Hakuro had landed the final blow.

"You got me," Rimuru said, grinning. "But I learned a lot. Thanks for the lesson."

Hakuro bowed slightly. "The honor was mine, Rimuru-sama. You've grown immensely in just one sparring session. With more practice, you might surpass even me."

Benimaru approached, a wide grin on his face. "That was incredible! Rimuru-sama, you almost had him!"

Rimuru smirked. "Almost isn't good enough. I'll get you next time, Hakuro."

Hakuro chuckled. "I look forward to it."

As the crowd dispersed, Rimuru stood in the clearing, his wooden sword resting on his shoulder. He felt a sense of accomplishment but also a determination to keep improving. The path ahead was long, but with allies like Hakuro, he knew he could handle whatever came his way.
